Answer Posted / tarun aggarwal ymca
If DC supply is fed to a transformer's primary, then inductive reactance X1 and magnetising reactance X0 becomes zero. The no load branch contain a parallel combination of R0 and X0. As X0 is zero so that the impedance of no load branch is zero. and current being the ratio of Supply Voltage and no load impedance is very high as it burn the primary winding.
